Dome hinges in Aluminium

Dennis will send me his set of Ali Dome hinges the next days.
I guess only the basic version without rods, springs, etc., But this is not the big problem; I will use springs from pencils and small linkage metal rods are already on stock!
The only thing to produce is a 5 or 6 mm solid rod! So drilling holes in it, another holes with threads and I am ready!! The  micro servos for them are here too!
